Bob, the Cox PT19's stab. is somewhat like that. With "up" input; it's leading edge actually drops below the pivot-point. Mine has what I'd say; a 30/70 split to where the pivot/hinge-point passes through the tail. Cox's design works.. and holds up to abuse.. which is a testament to good "Plastic Flying Model" engineering.
